The Identification of Travelling Waves in a Voltage Sensor Signal in a Medium Voltage Grid Using the Short-Time Matrix Pencil Method

Most of the fault wave localization methods are based on analysis line current transformed by transformers and limited to high voltage grids. Fault in medium grids is still being developed. This paper presents a new real-time algorithm for identification travelling waves distribution grid using signal short-time matrix pencil method. To obtain secondary side waveforms at substation, model resistive sensor broadband measurements from 10 Hz 20 MHz was The tested amplifies frequencies associated with more than utility frequency allowing identification. Short-circuit simulations IEEE 34-bus feeder performed test algorithm. developed method can detect even low amplitude.
